An application program interface (API) provides a set of functions for application developers who build Web applications on Microsoft Corporation's .NET™ platform.

Application program interface for network software platform

When an ad hoc network is formed between short range wireless devices, at least one device assumes the role of an ad hoc network information provider for the new piconet. In this role, the device allocates a browsing hierarchy of service classes in its service registry. The service classes will provide a record to characterize the ad hoc network. When a new wireless device arrives within the communication range of any member of the ad hoc network, its inquiry signals are answered by the first member detecting the inquiry. If that first member is an ad hoc network information provider, it responds with information accessed from its service registry characterizing the ad hoc network. If, instead, an ordinary device in the ad hoc network is the first to respond to the inquiry signals of the arriving device, the device responds with the address of the ad hoc network information provider. The arriving device then pages the ad hoc network information provider to obtain information characterizing the ad hoc network.

An application program interface includes a first class to provide information regarding a current HTTP request. The application program interface also includes a second class to manage HTTP output to a client and an object to provide access to server-side utilities and processes. Particular application program interfaces include additional classes to manipulate cookies, handle file transfers, provide exception information, or control operation of an output cache.

Application program interface that enables communication for a network software platform

A distributed network access system (30) in accordance with the present invention includes at least an external processor (42) and a programmable access device (40). The programmable access device has a message interface coupled to the external processor and first and second network interfaces through which packets are communicated with a network. The programmable access device includes a packet header filter and a forwarding table (50) that is utilized to route packets communicated between the first and second network interfaces. In response to receipt of a series of packets, the packet header filter in the programmable access device identifies messages in the series of messages upon which policy-based services are to be implemented and passes identified messages via the message interface to the external processor for processing. In response to receipt of a message, the external processor invokes service control on the message and may also invoke policy control (48) on the message.

A programming interface provides functions for generating applications, documents, media presentations and other content. These functions allow developers to obtain services from an operating system, object model service, or other system or service.

Programming interface for a computer platform

A system and method for enabling a zero configuration nomadic wireless and wired computing environment presenting a just works experience is presented. The system examines predefined user preference or profile settings to determine to which of a competing number of wireless networks available it should connect, and what type of authentication should be used for such connection. Nomadic wireless computing between infrastructure wireless networks and ad hoc wireless networks may be accomplished without further user intervention required in an auto mode. Also, both infrastructure only and ad hoc only modes are available through the system of the invention. Further, the user may set a preference for infrastructure or ad hoc modes in the auto mode. With an infrastructure mode preference set, the system will automatically detect and transfer connectivity to a newly available infrastructure wireless network if the user was previously operating off-line or in ad hoc mode.

A power management scheme for use in a wireless device reduces the power consumption of the network interface module of the wireless device by selectively putting the network interface module into a low-power state for an idle time. The length of the idle time is calculated such that the amount of delayed traffic data accumulated is expected to be less than or equal to a pre-selected threshold when the network interface module is put in the low-power state for the calculated idle time. The amount of delayed traffic data as a function of the idle time is modeled using average inter-arrival and service rates that are derived from traffic statistics data.

The present invention provides a directory service system for accessing a plurality of directory services in a uniform manner. Each directory service manages information relating to objects of that directory service. The type of information that a directory service manages for an object is defined by the object class of the object. An object class defines the properties (i.e., information) that a directory service manages for objects of that object class. Each property has a property name and property type. A directory service has a property value for each property defined by the object class of each object. The directory service system comprises a schema browsing component, a name resolving component, a binding component, and an extending component. The schema browsing component controls the retrieving of the property name and property type of each property of each object class of each directory service. A client of the directory service system uses the schema browsing component to retrieve property names and property types of the object classes. The name resolving component controls the receiving of a unique identifier of an object within a directory service and the locating of the object within the directory service. The binding component controls the binding to an in-memory object representing a located object within a directory service. The extending component controls the defining of new object classes and new properties for each directory service. A client of the directory service system uses the extending component to define new object classes and new properties.

Method and system for uniformly accessing multiple directory services

A system and method for enabling a zero configuration nomadic wireless and wired
computing environment presenting a just works experience is presented. The system examines
predefined user preference or profile settings to determine to which of a
competing number of wireless networks available it should connect, and what type of
authentication should be used for such connection. Nomadic wireless computing between
infrastructure wireless networks and ad hoc wireless networks may be accomplished without
further user intervention required in an auto mode. Also, both infrastructure only and ad hoc
only modes are available through the system of the invention. Further, the user may set a
preference for infrastructure or ad hoc modes in the auto mode. With an infrastructure mode
preference set, the system will automatically detect and transfer connectivity to a newly available
infrastructure wireless network if the user was previously operating off-line or in
ad hoc mode.

A method of network security policy administration for a network client uses a finite state machine to maintain the security policy information of the network client. Security policy information may originate in a remote source such a directory storage as well as, or alternatively, locally in cache and local store locations. The finite state machine has four states, Initial, DS, Cache, and Local, and transitions between states responsive to the availability of security policy information from the various policy information sources. Furthermore, security policy updates occur via a differencing mechanism, wherein only filters that have changed are updated, minimizing impact on unchanged policy filters and the traffic protected by them, and minimizing lulls in policy coverage.
